Stone: Elterwater Elterwater quarry

The Elterwater quarry is situated at the foot of the beautiful Langdale Valley with open views to the Langdale Pikes and has been worked since the middle of the 19th Century. Elterwater is a pale green stone, often highlighted by contrasting markings which emphasise its natural origins.

Elterwater has been used to add character and beauty to many domestic and commercial projects around the world for paving, flooring, roofing, cladding, walls, cills and worktops. Like Broughton Moor, Bursting Stone, and Brandy Crag, Elterwater is a metamorphic volcanic stone from the Ordovician period, and is thus 450-500 million years old.
